They are documentaries of rare and precious events: that of filmmakers manufacturing a documentary.

Of course, all movies by this criteria are, in a sense, documentary movies.

But what makes "White Wilderness" and "Ingagi" both documentaries despite the amount of fictionalization contained within them is that they function to lend the overall illusion of "real-life-ness" to the movie.

The fakery is not meant to be interpreted as fictional, but as factual.

And, more often than not, there's a base pleasure in the very attempt of forging a documentary that is, in itself, (perversely) purely documentary.
